Brachial palsy is the muscle weakness or paralysis that develops in the arm, forearm and hand in different degrees of severity due to the stretching of the nerve structures that start from the neck level of the baby’s spinal cord and extend from the armpit to the hand during a difficult delivery.
Its incidence varies between 1 and 4 in 1000 newborns. Factors that increase the probability of its occurrence can be listed as multiple pregnancy, large size of the baby, long-lasting difficult birth, entry of the baby into the birth canal with its legs, that is, inversion.
This condition may regress spontaneously up to 2 years of age in the majority of infants. This possibility is predicted by the examination of the baby. However, in any case, it is necessary for the baby to receive treatment in order to preserve the joint movements and have an upper extremity that can be used more actively. In infants and children who do not regress spontaneously or are not predicted to regress, some surgeries enable more active use of the arm.
